PLC Application And Study In Oil Tempreture Oil Pressure In Ore Grinder

Ore grinding occupies an important place in the manufacture of metallurgy and nonferrous metal industry .Status of ore grinders have direct relation with the production and economic-technical indicators. It is one of the most important path to improve the economic efficiency of ore dressing plant which make sure the good running of ore grinders. With the deep study and continuous improving of ore dressing automatin technique, exploitation of new type sensors, computer technique and PLC technique get deep application in control and protection of ore grinders.Plus with the new techniques and ore grinder,in the long run,digitization and intelligentization are the future orientation of the ore dressing.The present paper is based on grinding system of JinChuan Company. According to technical flowing and running situation of former facilities, employed the method that combine the scene controller and scene bus, which uses PLC as the core technique. Adopting new model sensor to collect data, PLC system to analyze, big screen to show results timely, realized the timely monitor to the facility's running. When the facilities trap in unusual, system will send stop instruction to electromotor, realize the facility stop protectively. The result of real running shows that PLC monitor warrantee the stable running of facilities, eradicate the breakdown completely, improve the economic benefit.
